Omio, the Berlin-based travel retailer selling more than 130,000 tickets per day, has joined Online Travel UK (OTUK), the industry association whose existing membership reads like a who's-who of online distribution: Airbnb, Booking.com, Expedia Group, Skyscanner, Trainline and Trip.com, among others.

The move, announced September 2, gives OTUK its most explicitly multimodal member to date. Omio operates three consumer brands — Omio, Rail Europe and Rome2Rio — alongside a B2B arm serving travel agents and transport operators. The company employs more than 500 staff across offices in Berlin, Paris, Prague, Melbourne, Bengaluru and Singapore.

Founded in 2013, Omio sits at the intersection of rail, coach, air and ferry distribution. OTUK said the company brings "an international and multimodal perspective, with first-hand experience of how travellers navigate transport systems across Europe, the Americas and Asia."

Why does multimodal membership matter for OTUK?

Until now, OTUK's roster has been dominated by accommodation-heavy and flight-heavy online travel agencies and metasearch players. Omio's arrival shifts the association's centre of gravity toward ground transport and multi-leg journeys — a segment where UK rail distribution has been a contested commercial battleground, with Trainline already a member.

The association framed the addition in terms of policy capability rather than commercial interest. "Broadening our membership strengthens our collective expertise and ability to engage with policymakers on the issues shaping the future of travel, while championing consumer protection, choice, value and digital innovation," OTUK said.

For sellers of travel, the signal is that rail and multimodal ticketing will likely feature more prominently in OTUK's lobbying positions — particularly as the UK reviews how transport ticketing, digital markets and travel regulation interact.

What is Omio arguing for?

Catriona Meehan, Director of Public Affairs at Omio, made the company's regulatory stance explicit in her September 2 statement.

"The way people plan and book travel is changing fast," Meehan said. "Travellers don't think in silos. They want the freedom to compare their options and find the journey that works best for them, whether that's by train, coach, plane or ferry."

She pointed to looming UK regulatory decisions as the rationale for joining. "With major decisions ahead on how transport, digital markets and travel are regulated in the UK, it's more important than ever that travellers continue to benefit from open markets, real choice and strong competition."

Meehan also stressed that national rulemaking increasingly collides with international travel behaviour. "But while those decisions may be made nationally, travel itself is increasingly international. People cross borders as readily as they move between travel modes, and the rules that shape the market need to recognise that reality," she said.

What are the distribution implications?

Omio's arguments — open markets, comparability, competition — map directly onto the commercial questions that determine how rail and multimodal inventory gets sold: access to carrier ticketing APIs, the terms intermediaries face, and whether incumbents or aggregators control the customer relationship.

The company's B2B services, which supply travel agents and transport operators with ticketing capability, mean its regulatory positioning in the UK could affect not just its own consumer brands but the distribution partners that rely on its rails.

The full OTUK membership now comprises:

• Airbnb
• Booking.com
• eDreams ODIGEO
• Expedia Group
• Kiwi.com
• Lastminute.com
• loveholidays
• Omio
• On the Beach
• Skyscanner
• Trainline
• Trip.com

With UK policymakers set to take decisions spanning transport, digital markets and travel regulation, Omio's seat at the OTUK table positions multimodal distribution interests — and by extension the agents and operators plugged into its B2B network — to shape the terms under which cross-border, multi-mode journeys are sold in Britain.
